【摘要】 实时准确获取农产品在供应链环节中的环境参数是农产品安全可追溯系统透明化的瓶颈之一。射频识别(RFID)技术可与传感器技术相结合,应用于农产品质量安全追溯系统,对温度、湿度等重要参数进行检测、记录,并通过无线通信的方式进行识别。本文综述了集成传感器电子标签的国内外发展现状,分析了技术关键点,指出了目前存在的问题以及解决问题的建议。更多还原

【Abstract】 It is a bottleneck of transparency of the agricultural traceability system to acquire environmental parameter of agricultural products in the supply chain real-time and accurately.Radio frequency identification(RFID) technology has been a research hotspot in recent years as a new automatic identification technology.It is significant to combine RFID tag with sensor to the agricultural products traceability system.It can detect and record temperature,humidity and other important parameters,and it can be identified by wireless communication. The current development status of this kind of tag was reviewed both in China and other countries.The key technology is analyzed,and the existing problems and solutions are pointed out.It provides a reference for further research on RFID tags integrated sensors.更多还原
